# updateStatus

Must be called by physical battery controller when battery state has changed significantly.

## Declaration

```occ
virtual void updateStatus(
 void); 
```

## Overview

Overview The system will not poll this object for battery updates. Rather \ the battery's controller must call updateStatus() every time state changes \ and the settings will be relayed to higher levels of power management. \ The subclassing driver should override this only if the driver needs to add \ new settings to the base class.
